“…The development of the SMA-containing SMEP hybrids started with the investigations of laminated beams [178,208,209,210] followed by 2D (shell) [211,212] and 3D structures [213] and devices [178]. These works contributed to clarify open issues with respect of embedding, positioning, content, maximum straining, minimum bending radius, actuation capability-related properties, etc.…”

Shape memory polymer (SMP) is capable of memorizing one or more temporary shapes and recovering successively to the permanent shape upon various external stimuli. Beside of the above mentioned one-way variants, also two-way shape memory polymers (SMPs) and shape memory (SM) systems exist which feature a reversible shape change on the basis of "on-off switching" of the external stimulus. The preparation, properties and modelling of shape memory epoxy resins (SMEP), SMEP foams and composites have been surveyed in this exhaustive review article. The underlying mechanisms and characteristics of SM were introduced. Emphasis was put to show new strategies on how to tailor the network architecture and morphology of EPs to improve their SM performance. To produce SMEPs novel preparation techniques, such as electrospinning, ink printing, solid-state foaming, were tried. The potential of SMEPs and related systems as multifunctional materials has been underlined. Added functionality may include, among others, self-healing, sensing, actuation, porosity control, recycling. Recent developments in the modelling of SMEPs were also highlighted. Based on the recent developments some open topics were deduced which are merit of investigations in future works.

“…A major disadvantage of these studies is that they do not address the force transmission from actuator to reinforcing fabrics since the actuators are placed in the skin of the morphing wing. However, a breakthrough in terms of higher force transmission from actuator to FRP is only possible if SMAs are textile-technically integrated into reinforcing fabrics [21][22][23][24].…”

The process of integrating smart materials into fiber-reinforced plastics has been used increasingly to create different high-performance products for lightweight applications. This paper presents the development of an adaptive morphing wing based on fiber-reinforced plastics with shape memory alloys integrated into the reinforcing fabrics. Two types of preforms with varying numbers of integrated weft yarns in shape memory alloys were manufactured for a wing structure on a weaving machine using the pleated woven fabric technology. Subsequently, the realized preforms were infiltrated by a thermoset matrix and characterized mechanically to derive a preferred variant. After developing the adaptive morphing wing, its deformation behavior was characterized by varying current flow and time through shape memory alloys. Results revealed that maximum deformation of the investigated adaptive morphing wing was achieved at a current flow and time of 1 A and 60 s, respectively.

“…Anisotropic material properties of FRPs allow the development of material- and energy-efficient components, which have been employed in automobile, aerospace and plant engineering industries for the past two decades [3]. Besides meeting specific material design requirements, FRPs offer the possibility of functionalizing lightweight constructions by integrating functional materials as part of their layer construction [4,5]. Thus, active functional constructions are realized, and the application spectrum as well as market potential of FRPs is consequently increased.…”

“…The functionalization of FRPs by sensors aims primarily to develop sensor networks, for example in the form of carbon rovings or metal wires, in order to enable structural health monitoring. Apart from integrating sensory functional materials, the functionalization of FRPs with actuator materials poses a promising approach for FRPs to meet the requirements of new fields of application, such as joint-free and actuator-acting FRPs components [5]. Piezo-ceramics, piezoelectric polymers, electro-/magnetostrictive materials, shape memory polymers and shape memory alloys (SMAs) are among several potential actuator materials for the functionalization of FRPs [6].…”

Textile-based lightweight structures offer various possibilities for the design of tailored structures by the selective choice of materials and their processing into textile semi-finished products and fiber-reinforced plastics. Lightweight structures with a high mechanical load capacity are feasible by developing fiber-reinforced plastics with adaptive properties that are able to adapt their characteristics, e.g. geometry or stiffness, to external influences. Thus, the application potential of fiber-reinforced plastics can be further expanded. In this paper, we present novel adaptive fiber-reinforced plastics based on textile semi-finished products with integrated shape memory alloys and their mechanical characterization. The shape memory alloy is textile technically integrated and converted into friction spun hybrid yarn. Next, the produced hybrid yarn is integrated with plain, twill and satin woven reinforcement fabric in the weft direction during the shedding operation in weaving. Adaptive fiber-reinforced plastics are developed by infusing textile semi-finished products. Subsequently, the mechanical characterization of the adaptive fiber-reinforced plastics is carried out. Results show that, by integrating shape memory alloys into adaptive reinforced fabrics, the mechanical performance of fiber-reinforced plastics can be tailored.
